Latest Patents
Yoo Eup Hyung holds a patent for a lithium-ion battery with improved safety. This invention utilizes one or more additives in the battery electrolyte solution, where a lithium salt is dissolved in an organic solvent, which may contain propylene carbonate. For instance, a blend of 2 wt % triphenyl phosphate (TPP), 1 wt % diphenyl monobutyl phosphate (DMP), and 2 wt % vinyl ethylene carbonate additives has been found to significantly enhance the safety and performance of lithium-ion batteries using a LiPF salt in EC/DEC electrolyte solvent. The invention relates to both the use of individual additives and blends of additives at concentrations of 1 to 4 wt % in the lithium battery electrolyte. These additives suppress gas evolution in the cell, passivate the graphite electrode, and protect it from exfoliating in the presence of propylene carbonate solvents in the electrolyte, while also retarding flames in lithium batteries.
